Manuscript CB 88, which combines the Odes, the Epodes, and the Carmen saeculare, a piece interpreted by children's choirs of the Roman nobility during secular performances, is an unusual example of a Horace manuscript from the turn of the 10th to the 11th century. Its many marginal and interlinear glosses, which frequently consist of scholii by Pseudo-Acro, explain the verses and praise their metrical accuracy and verbal virtuosity. The alphabetical tables and the title were added in the 14th century at the end of the volume. (mes)
